I apologize if this was already commented on but in checking the Health app on my phone I now see that the watch is recording my heart rate every 10 minutes regardless of activity. I know many complained of that function being disabled with 1.0.1. It was not a problem for me and I was happy with it recording while I was at rest or during exercise activities. I just hope that the return to every 10 minutes does not negatively impact battery life.
